My invention relates to'=devicesfor impregnating a thread with the liquid, 'u'sua'lly'oil or'water, prior to textile use.

The main purpose of my invention is to a throw off excess liquid from the thread by centrifugal force. v

A further purpose is to combine a centrifugal device with wipingdevices to remove excess liquid from a thread; I I

A further purposeis to submerge a thread uniformly for the oiling or Wetting-operation and permissibly to Wipe it, removing surplusliquid from its surface by centrifugal means. i

:In bothv embodiments lfprovide a container 9 for a pool of liquidlO b'y which'athread :11is to be wet or oiled. I Thethread is passed through the liquid 'froma guide 12 beneath 50 "a float =1'3 to devices b'y which the excess liquid liquid.

From beneath the float in the illustrations the thread passes over or about wiping devices "shown as ribs 17 or 17 (Figures 1 and :2'or5 and andpins 18. The latter ex the grooves {19 or 19 between the ribs. The ribs and grooves are shown ascurved inFiguresl and 2'and as straight in Figures 5 and' 6,but ineither event'the grooves drain into spaces '20 forming channels for return fiow'ofliquid between themes-anemia or border 21, This rim orborderaffords an extension of or maybe connected "with the sides 22 of'the containerand at and nearthe right hand end it is used for a further pur- F A pose hereinafter described;

The portion "23 of therim is'diagonally apertured at 24: and the thread passing through it is directedby'a'r'emovable guide 25 resting in an'opeiiing26 within the endof 'the'drain and guide board 27 o'r 27. This 0 guide issub'jectto considerable wear and has therefore been made replaceable. r

As thus far described the device functions in muchthe same way-as thatofmyapplication for patent for thread oiler or moistener,

filed'Februar'y-20, 1926Serial Number 89,529.

However, I find it'desirable in inany p'laces torem'ove a larger amount of theliquid from the *thread than is removed by the wiping operation of this application in order to prevent spraying of the excess liquid carried throughby the thread. 1

Though it-maybequit'e desirableto oil or wet the'th'read thoroughlyany liquid ca'rried by itmerely uponth e surface is not useful to condition the thread and unnecessarily oils or dampensthe article being knit. 'Theiexcessive amount of liquid carried through is sprayed over the machine which is being fed, objectionable both because'ofthe waste and .30 I satisfactorily.

because of the untidyness and injury caused by the spraying.

In both of my embodiments I show centrifugal means 28 or 28 for removing the excess liquid from the thread before it leaves the device and in which liquid isconserved by the simple expedient of catching the oil sprayed centrifugally.) The axis of the centrifugal 7' device need not of coursebe' vertical to pera extension will answer but a vertlcal spindle form the function. .Anyother direction of permits the spray from it to be caught easily and completelyby the protecting side ande'nd rim 'andprovides for return ofthe spray caught to thepool. i' 'i V 7 r In the-embodimentr'shown in Figures 13 the centrifugal drier comprises a spool 29 mounted upon aspindle 30 and having a preferably tapered surface 31 about which the thread is turned. I showa-singleturn only but by experiments have foundthat aplu- 'rality of turns is entirely practicable and se-' cures a, more complete removal of surplus liquidfromthe thread than 'does'a single turn.

tendency of thethread to' climb the spool,

for, the same reason that causes a belt to ride on the larger diameter of a pulley. This separates the convolutions of the thread quite The lower part of the spoolfis flanged at 32 for, the purpose of providing a drag I agalnst excessive turningof the spool after the .pull upon the thread has ceased. This is particularly desirable in feeding full-fashionedmachines where the feed-is intermittent and where as the pull ceases the friction of the flange upon the base 33 stops the rotation of the spool' quickly. There is a tendency of thespoolto lift duringthe feeding to some such position as that shown in Figure 2, in which positionthe drag is not effective. The use of a drag all the time or a part of'the time or not at all will be guided, of course, by the need in the use made of the device.

The drag of courseiinitially delays starting of the .spool. V

p The spindle 30 is shown as threaded at 34 so as to fit into a nut 35 which is cast in the glassand which-is provided with projections so that it will hold securely within the glass.

The spindle is extended above the spoolat 30 to provide a'mount for a cap 36 into which the spool projects so as to protect the thread from accidentalwhipping into the space above the spool and from catchingbetween ityandthe top. prefer to concaveithe under r side ofzthe'cap at 37 andfurther recessit-at 38 to give space for .thejspool to rotate within it without engagement with-or without undue'frictionwiththe top, The top is threadedlupon the spindle at 39 and is locked in position'by nut 40.

' In operation the greater part of the excess liquid is removed by centrifugal'force and all of it could be removed in this way. However,-:for thefpurpose of gettingvad'ditional.

dragFeasily I find, it desirable to. combine this centrifugal action with preliminary wiping of the thread which also drains oifexcess liquid, using both the centrifugal device and the wiper to cause a drag upon the thread so as to prevent excess throwing of the thread and relievingthe splashing both by removal of the excess liquid and by the reduction or prevention of whipping-of the thread such as would take place with overthrow. 7 .I find that I can sufliciently "saturate the body of the thread with the liquid in Lwhich-i-t is submerged to eflectively prepare the thread for the next textile operation whatever it be.and withoutinterference with this conliquid from 7 ditioning can remove the surplus the surface of the thread.

A considerable portion of the excess liquiddrains from' the thread uponthe ribs and any remaining excess is removed by'centrifugal force as the thread follows the circular path about the spool one or more times ac; cording tothe need and desire of the designer or operator. One turn about the spool provides a freer running mechanlsm w th less drag but with less removal of excess. whereas two or -more turns of the thread-about the chine or any winding or baclrwinding opera-;; r

tions'and considerable drag being'needed where the conditions of feed are likely to cause overthrowing. 1

I have made tests by weight which show I p 120.

that the amount of liquid carried by the thread can be controlled very exactly and can be varied within wide limits, securing the best possible results with a minimum of liquid and without splashing or spraying between the drier and the machine. V

I have found that the friction flanges at the bottom of the spool serve also to-guard against the. thread getting-underthe spool and thatthe drag of the wipersserves not I I only to drag the threadbut, through it, to

drag the spool also. The combined drags must of course be kept less than the permissible pull.

I recognize that my invention is applicable quite widely to all feeding operations where a thread is oiled or otherwise conditioned by liquid treatment by contact, submergence or otherwise, whether the feed be continuous or intermittent and that the benefit of my invention is greatest where the conditions are most diflicult.

It, will be evident that making the spindle guide rotary greatly reduces the friction of the thread but that primarily my invention comprises giving a thread circular movement I at a relatively high rate of speed to cause the thread to throw off liquid by centrifugal force. 7

In view of my invention and disclosure variations and modificationsto meet individual whim or particular need will doubtless become evident to others'skilled in the art, to obtain part or all of the benefits of my invention without copying the structure shown, and I, therefore, claim all such in so far as they fall within the reasonable spirit andscopeof my invention. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is j 1. The method of removing excess liquid from a moving liquid-treated thread which consists in guiding the thread about a circular path and in utilizing the centrifugal force secured to throw off excess liquid.

2. The method of removing excess liquid from a moving liquid-treated thread passing about a support which consists in causing rotation of the support by pull upon the thread and in utilizing the centrifugal force secured to throw off excess liquid. 7 I

8. The method of removing surplus liquid from a thread which has been liquid-treated and which is being fed, which consists in giving the thread circular movement about a relatively small axis to throw off excess Water by centrifugal force.

4. The method of removing excess liquid from a moving liquid treated thread which consists in guiding the thread about a circular path of larger diameter in one part than another of that within the turns of the thread, causing the thread to separate axially of the path by the difference in diameters and to throw off surface liquid by the centrifugal force produced.

5. A centrifugal drier for thread comprising a rotatable guide providing a circular path for the thread and means for pulling the thread about the path, and a drag for the drier to control overthrow. i

6. A centrifugaldrier for thread comprising a rotatable guide providing a circular path for the thread and means for pulling to control overthrow and a drag for the thread wiping liquid from its surface.

7. In a device for conditioning liquid treated thread, a guide for the thread directing it about a complete circumference so as to throw off liquid from its surface by cen-- trifugal force.

8. A mechanism for 'cOllClltlOIllIlg thread, a centrifugal device'for removlng excess liquid from the thread guiding the thread about an upright axis and a guard above and about the centrifugal device adapted to catch and con-' serve the liquid.

9. In a device for conditioning thread carrying a surplus of liquid, a rotary guide for the thread adapted to throw off excess liquid by centrifugal force and dragging means tending to restrain rotation and reduce overthrow of the thread.

10. In a device for conditioning thread carvice about which the thread is turned and by which liquid is thrown from the thread centrifugally.

13. In a conditioning device for thread carrying moisture in excess of that required for the operation in which the thread is to be used, a guide about which the thread is coiled l .andby which the threadis given circular movement to throw off the water by centrifugal force and means for pulling the thread.
